Cemlyn and Llanrhwydrus circular walk

A truly atmospheric three-mile walk, where you'll have the chance to see spiritual sites, rock formations and wildlife on the lagoon. If you time it right you'll catch the sun setting over the Irish Sea.


Please note that Bryn Aber car park is liable to flooding. Please check high tide times before your visit.

Start point

Bryn Aber car park, grid ref: SH329936

Step 1

From the car park, walk out past the monument towards the headland.

Step 2

Turn left through the kissing gate and either follow the coastal path or walk along the beach.

Step 3

Enjoy the wonderful sea views as you walk along the coast. If you have time, it's well worth making a short detour to Llanrhwydrus Church. This lovely little building is one of Anglesey's oldest spiritual sites and one of very few pre-reformation churches on the island.

Step 4

When you reach the little bay of Henborth be sure to look for the Henborth drumlin, a rock formation that looks like a beached whale. Turn left through the kissing gate.

Step 5

Walk on through the kissing gate towards Hen Felin (Old Mill) and cross the bridge. Turn left onto the lane and walk back towards Cemlyn Bay and the National Nature Reserve sheltered by the shingle ridge.

Step 6

After you pass Fronddu, turn left up the lane. This takes you past the Cemlyn lagoon, established in the 1930s by Captain Vivian Hewitt of Bryn Aber.

Step 7

Follow the lane over the causeway and back to the car park.

End point

Bryn Aber car park, grid ref: SH329936
